Description: Intermediate form between D. bergennii and D. quinqueramus with central-area 1-2x free ray length).

Remarks: As observed by Muller (1974) and Theodoridis (1984) D. berggrenii grades into D. quinqueramus, and is probably not a separate species. It is, however, only common in the lower part of the range of D. quinqueramus; and discrimination of it is easy.

Range: NN11A.
